Explosion-proof
loudspeaker

15 and 25 Watt  

The loudspeaker with built-in 100V transformer allows the connection to 100V loudspeaker systems according to VDE 0800 T1: 5.89, which are installed in explosive environments.

Explosion protection class II 2 G Ex demb IIC T4, T5, T6 allows the loudspeaker to be operated in Ex areas of the zones 1 and 2.

The housing material is electrically conductive and UV-resistant solid plastic. It is mounted at the place of use by means of a swivelling mounting bracket. These brackets and the fastening screws on the housing are made of stainless steel.

Designed for extreme conditions.

Manufactured according to EN 60079

Unique and eco-friendly

*in 15 W version

40% less energy consumption for the same sound pressure level*.

The purchase and operating costs for amplifier units and peripherals are correspondingly lower.

As the only one in his class the Neumann Ex loudspeaker in both versions has an identical sound pressure level of 119dB(A). This allows up to 33 units* to be connected together.
